Dynamic Compression and the "Lay Person"

I thought this would interest a few people here. As we all know dynamic compression, almost always sucks. I decided to do a little study on the preferences of the "lay person" or non-audio nuts.

I took an extremely dynamic Steely Dan song and compressed it (just dynamics) and then perceptually level matched the original song and the compressed version and started testing on my reference headphones (chosen for their linearity in frequency response). Right now the study is in its pilot stage (the reason why I am not going into full details). I will say though so far even if the participants consistently fail an ABx test between the two files and hearing differences it is statistically likely that in a blind comparison the subjects do prefer the uncompressed file. Due to this being a pilot study the results aren't generalizable enough yet, but I am working on that.

Hopefully, next semester when I have more time to commit to this project I will get more subjects and perhaps even the recording companies will listen, but that is probably being idealistic.

Lastly, sorry if I have posted in the wrong forum, but music seemed the perfect place for this as its ruining our music as I am sure most of you know!

Excellent post-

Any chance you would be willing to share the spreadsheet with some of us? I am curious to see how it broke down.

Also, was the comentary of the test subjects recorded? It would be interesting to see what the perceptual differences were.
